Some compounds of type M(Lss)2Br4, where M is Mn(II), Fe(II), Co(II), Cu(II), Zn(II) and Cd(II) and HLss are dithioacetylacetone, were obtained by passing hydrogen bromide, adding bromine and passing hydrogen sulfide through an ethanolic solution containing an anhydrous metal bromide and acetylacetone. Such compounds, which seem to be isostructural with tetrachlorobis-(dithioacetylacetonato)iron(II), are stable. They are all of high spin, and their infrared spectra show characteristic bands at about 1200, 1000 and 860 cm−1. CuI(Lss)2Br3 was also obtained from cupric bromide by the same method without using bromine, but from cupric chloride, an isostructural complex was not obtained but [Cu(C5H8S2)Cl]n. Electronic spectra are also shown and discussed.
